It's not about dropping a bunch of money on something with a label on it. It's about buying clothes that fit well, make your body look good and last. My mother bought a pair of slacks at the Goodwill that are well made and she was showing me how they don't sag because of how they are stitched. If you are happy wearing clothes from Walmart, that's great! Those in the business world can be judged by how they look and dress (especially in sales) and it can make a difference for them.
